During IDEA 2019, Autefa Solutions will present ways to increase productivity as well as energy savingse technology for spunlace production lines. Autefa Solutions’ high-speed Webforming sub-system, consisting of Injection card and Crosslapper CL4006 SL allows customers to keep or extend their leadership in the highly competitive spunlace market. The proven technology runs in several production lines all around and boost the speed and production in existing and new spunlace lines. The main challenge in such high speed lines is to keep fibers at any time and process stage under control. Autefa Solutions Injection card enables (Drylaid) web forming at very high production levels. The Injection Card uses a unique combination of mechanical and aerodynamic principle for a gentle carding action. The Injection Card delivers a quality web at the highest production with a better MD/CD ratio.
With the Topliner CL4006 SL Autefa Solutions offers a crosslapper with special features for spunlace applications. Highest layering speeds and precise weight distribution are possible thanks to the integrated drafting unit, compensation belt, antistatic equipment and new designed transport aprons. These features are very important—especially for lightweight applications in spunlace lines—and ensures the infeed speed up to 130 m/min.
With the V- Jet injector from Autefa Solutions water pressure can be reduced while maintaining same fabric strength. The energy cost saving potential using V-Jet technology is in the range of 20 - 30%.
In addition, the water consumption is reduced by 10% when using the same nozzle diameter and pitch. Autefa Solutions Square Drum Dryer SQ-V combines the advantages of a horizontal dryer with the lower space requirement of a conventional drum dryer. The nozzle system uniformly distributes the airflow in terms of speed and temperature throughout the whole working width, providing best spunlace web and surface quality results. The Square Drum Dryer SQ-V has different heating zones and operates each heating zone with optimal drying conditions. Due to the small footprint the Square Drum Dryer SQ-V is a solution for energy optimizing of existing lines.
